When the man wouldn't calm down, officials said two Tasers were deployed. One missed, the other one hit the man, but it had no effect, possibly because of his thick clothes, officials said.

The man then used the machete to cut the wires of the stun gun. That's when one officer started shooting, officials said.

"I heard these bang, bang, bang," shared Wes Schraden. "Then there was like a pause and then bang, bang, bang, again."

"Saw the police down the corner, pretty sure I seen their guns raised," added Moyer. "As I was running back through the yard, the shots just kept going and going."

"He continued to be very combative, bringing the machete over his head and advancing with what's being described as a chopping motion toward the officers," said Martin. "These officers were in peril. They were in jeopardy."

According to authorities, another Taser was fired and two other officers fired multiple shots at the man. Neighbors reported hearing between five and 10 shots fired. Martin said 13 shell casings were found at the scene.

"They were laying on top of him, holding him down," shared Schraden. "He was resisting 'cause there was at least five cops."

"I seen some guy being handcuffed and laying on the ground," described Moyer."Even though he was handcuffed at the scene, he was still combative and still thrashing about," added Martin.

The man was taken to a nearby trauma center, where he died around 2 p.m. Two officers were taken to the hospital after they touched the man's blood. Investigators said four officers -- two who fired stun guns and two who discharged handguns -- have been placed on administrative leave until the investigation is complete.

"At this time, this appears to me to have been a totally justifiable response by law enforcement," stated Martin.

The man was described as being Hispanic and in his 30s or 40s. His girlfriend was being questioned by authorities Thursday night

Investigators said Allentown officers encountered the man Wednesday, a half-mile from Thursday's shooting scene. We're told police followed him to his nearby home.

"He was acting what was categorized as strangely," explained Martin. "Appeared to have had some mental health issues. They were concerned about him."

The machete is being processed for fingerprints and other evidence.
